HEARD, Thomas Jefferson, physician, born in Morgan county, Georgia, 14 May, 1814. He studied medicine at Transylvania university, and began practice in Washington, Texas, in 1837. He received the degree of M. D. from the University of Louisiana in 1845. In 1857 he removed to Galveston. He exerted his influence to modify the treatment of malarial fevers in the southwest, and introduced into Texas the treatment by quinine, opiates, ammonia, and salts, in the place of bleeding, purgatives, and mercury. In 1868 he contributed to the "Transactions" of the American medical association a paper on " The Epidemics, Topography, and Climatology of Texas," containing observations on the yellow fever, and in 1869 a more general article on epidemics and climatology. He held the chair of the theory and practice of medicine in the Galveston medical school in 1866, and that of materia medica and therapeutics in the University of Louisiana in 1876, but resigned his chair in each of these colleges after delivering a single course of lectures. He was active in organizing the Texas medical association, and was its first president.
